NI 9234 Operating Instructions and Specifications 22 ni.com
IEPE compliance voltage.................. 19 V max
If you are using an IEPE sensor, use the following equation to make
sure your configuration meets the IEPE compliance voltage range.
(V
common-mode
+ V
bias
± V
full-scale
) must be 0 to 19
Overvoltage protection (with respect to chassis ground)
For a signal source connected
to AI+ and AI– ........................... ±30 V
For a low-impedance source
connected to AI+ and AI– .......... –6 to 30 V
Input delay ........................................ 38.4/ f
s
+ 3.2 μs
where V
common-mode
is the common-mode voltage applied
to the NI 9234
V
bias
is the bias voltage of the IEPE sensor
V
full-scale
is the full-scale voltage of the IEPE sensor
